The documents about CIA dealings with the film now titled "Zero Dark Thirty" were "inadvertently overlooked" in response to a Freedom of Information Act request and lawsuit filed by the conservative watchdog group Judicial Watch, Justice Department attorneys said in a motion filed in federal court in Washington Tuesday afternoon (posted here).

"The CIA discovered a 4 to 5 inch stack of records potentially responsive to plaintiff’s FOIA request that had been inadvertently overlooked during the CIA’s search," Civil Division attorney Marcia Berman wrote. "The CIA is continuing to look into the circumstances of the discovery of the new documents to ensure the adequacy of its search."

A CIA spokesman said the agency does not comment on matters in litigation.
